Garmin eTrex Vista HCx Guide - Version 1 www.besthandheldgps.tk Neither deep foliage nor steep canyons will faze the rugged Garmin eTrex Vista HCx navigator. Equipped with a high-sensitivity, WAAS-enabled GPS receiver, the unit locates your position quickly and precisely and maintains its GPS location even in heavy cover. The advantage is clear: whether you're traipsing through thick woods or strolling near tall buildings and trees, you can count on the Vista HCx to help you find your way when you need it the most. The Vista HCx also includes a built-in electronic compass that provides bearing information even when you're standing still, along with a barometric altimeter that tracks changes in pressure to pinpoint your precise altitude. You can even use the altimeter to plot barometric pressure over time, which can help you keep an eye on changing weather conditions.
